Hi Jim,
Actually, I don't see anything wrong with the internal structure having
a different type than the interface, as long both types are big enough
to hold the possible values (in this case 0 and 1). Though, as you
pointed out, testenc needs to be fixed to use spx_int32_t instead of
int. I'll change that.

...reated differently than
other, similar parameters. It would seem like the most intuitive approach
would be to match the interface to the structure.
This is a trivial point, of course. I have attached a patch to the two TI
interface files, which adds the configuration for the filter, sized as
spx_int32_t. I also included the modified files (I know that you have had
some trouble with patches that I have sent before).

Hmm, I always assumed there wouldn't be any overflows. What parameter
range are you using that causes them? I can always switch to 32-bit, but
I prefer 16-bit for memory size reasons (I'll switch if there's no other
option).

Hi everyone,
I'm about to release version 1.2-beta1 (which I could have called
1.1.13), which includes many, many changes. It would help if everyone
could give the svn version (http://svn.xiph.org/trunk/speex/) a try and
see if it works fine. I'll check my email next week when I'm back from
some vacations and if nothing bad has been reported, I'll make the release.
Have fun,

In-band user data
...bits as size, then advances
8*size + 5 bits.
First of all, shouldn't that be 5 bits for size (to match manual)? And
where did that '+ 5 bits' come from?
Next, and slightly unrelated question:
Why does
int jitter_buffer_update_delay(JitterBuffer *jitter, JitterBufferPacket
*packet, spx_int32_t *start_offset);
include the packet parameter? It's not used in the code, and it also
makes the API slightly confusing as it's very unclear what that
parameter should be :)

4kbps sounds robotic on TMS320C64
...c? If possible, can you try encoding on one and decoding on
the other, just to see whether the problem is when the encoder or the
decoder? Also, just in case it helps (but I doubt it),
try editing fixed_generic.h and change:
#define SHL32(a,shift) ((a) << (shift))
to
#define SHL32(a,shift) ((spx_int32_t)(a) << (spx_int32_t)(shift))

[patch] Mac Universal Binaries
Hi all,
Speex currently decides endianness at configure-time. This causes the
ppc half of Mac universal binaries to have some endianness problems.
Most notably, the header built by speex_packet_to_header() has
incorrect byte-ordering.
This Apple developer page describes the incantation that can be used
to build universal binaries on Mac. It also highlights the
configure-time versus compile-time

c) assumes that I won't just change the call to say spx_int32_t instead
of "int" ;-) It was always meant to be 32 bits anyway.

I guess I should deal with it at some point, but I'd like to know what
the RTP RFC says first....
